Member Function Documentation

void dtn::net::LOWPANConvergenceLayer::__cancellation	(	)
throw	(
	)

protectedvirtual

This method is called after componentDown() and should should guarantee that blocking calls in componentRun() will unblock.

Implements dtn::daemon::IndependentComponent.

Definition at line 303 of file LOWPANConvergenceLayer.cpp.

References _running, and ibrcommon::vsocket::down().

Here is the call graph for this function:

void dtn::net::LOWPANConvergenceLayer::componentDown	(	)
throw	(
	)

protectedvirtual

This method is called if the component should stop. Clean-up code should be inserted here.

Implements dtn::daemon::IndependentComponent.

Referenced by ~LOWPANConvergenceLayer().

Here is the call graph for this function:

void dtn::net::LOWPANConvergenceLayer::componentRun	(	)
throw	(
	)

protectedvirtual

This is the run method. The component should loop in there until componentDown() or __cancellation() is called.
